The birds of Varrio Nature Reserve have been monitored through spotwise and blockwise counting lines for 22 years, over 1985 to 2006 (click the above table once or twice, to get it bigger). Single, but regular bird observations have been recorded altogether 13,725 observations.

The used method overestimates some noisy species like Cuculus canorus, and underestimates others, which are silent in June, like Parus cinctus. However, there are some interesting details in the table. Like the Siberian jay, Perisoreus infaustus. It is visible in the forest all the year round. It is number 21 in the table with 55 pairs, less common than we would have expected. - In the photo a Siberian jay chick from 2006 breed on Rakitsa hill.

Maybe the most striking observation is for the game birds Willow ptarmigan (Lagopus lagopus) and Capercaillie (Tetrao urogallus). It must be remembered that Varrio Nature Reserve was established in 1981, and since then hunting of game birds has been eliminated (partillay until 1995, and totally since then). Willow ptarmigan is number 28 and Capercaillie number 35 of the Varrio birds. Willow ptarmigan is met on the bird counting lines only 1-2 times per year, Capercaillie on average only once a year.
